Answer:
FALSE
Explanation:
Energy is inversely proportional to wavelength.
∴ Waves with longer wavelengths have less energy than waves with shorter wavelengths.
Explanation:
chromatoghraphy is a laboratory technique for the separation of mixture... ...
chromatoghraphy may be preparative or analytical. The purpose of preparative chromatoghraphy is to separate the components of a mixture for late use, ans is thus a form of purification..... I is your answer it may help you

Answer: option (4) The reacting particles have more energy and
collide more frequently.
Explanation:
1) In order to a a reaction happen, the reactants must reach the activation energy, which is the energy needed to form the activated complex
2) Then, the higher the energy of the reactants, the less the gap between the energy of the reactants and the activation energy.
3) As per the collision theory, the reactant molecules must collide with energy at least enough as to reach the the activation energy.
4) The kinetic energy of the molecules is higher as higher is the temperature.
Then, you conclude that when you increase the temperature, the molecules will have more energy, will move faster, will collide with more energy, and will produce more effective collisions, which increases the rate of reaction.
